TRK 18 is a neutral, bistable, remanent, electromagnetic relay for DC coil energizing with one change – over contact system. The great advantage of the bistable relays over monostable lies in continuous operating without energizing. Bistable relays shall be energized with a brief DC voltage impulse, this saves coil energy and reduces operating costs. The self-heating of this relays no longer needs to be taken into consideration, what also enables high density of electronics components on PC board. Furthermore, if the power supply voltage fails, the switching status is maintained. As a switching element with ability of galvanic separation it is designed to control devices with medium power consumption. It can be soldered directly onto the printed circuit board used in industry, bureau appliances, data processing, automotive industry, gas heating equipment, safety and medicine devices and for general purposes. In case of full load on contacts and operating with max. switching rate and max. ambient temperature it is recomended to open the vent hole provided for this purpose after the relay is mounted on the PCB and the cleaning process is completed.
